We have Trend Micro WFBS advanced and use connect to our contractor's VPN via Juniper SSL VPN. However we are getting

"Your computer does not meet the following security requirements. Please follow the instructions below to fix these problems. When you are done click Try Again."

It seems as though Host Checker is not recognizing the AV. it is updated 8.977 and the server is 360 confirmed that it is updated to the fullest by Trend Micro Support. Anythoughts why or how to resolve this while I wait on a call from contractor's level 2 and 3 dept?
